Resum: Vesicoureteral reflux (VUR) is one of the most common ailments in children. Evidence-based guidelines recommend conservative treatment in children with VUR, followed by endoscopic surgery in those with breakthrough febrile urinary tract infections (UTIs). Despite this fact, the management of VUR is still controversial. Our objective is to evaluate the conservative strategy in children with primary VUR in terms of renal function and scarring, and identify factors associated with poor prognosis in those children. A retrospective study was carried out in a tertiary center in children with primary VUR under conservative strategy treatment from 1989 to 2015. Data extracted included age of presentation, family and prenatal backgrounds, radiographic evaluation including ultrasound (US), dimercaptosuccinic acid (DMSA) scans and voiding cystourethrogram (VCUG). The SPSS program was used for statistical analysis. Two-hundred and five patients were diagnosed and followed a conservative therapy scheme (49. 8% males, 50. 2% females) after febrile UTI (73. 17%) or prenatal diagnosis (26. 83%). VCUG showed 53. 20% of low-moderate VUR grade, 46. 80% high VUR grade. Renal damage was present at diagnosis in 40. 89%. Mean follow-up reakthrough recurrent febrile UTIs and underwent surgery. Conservative therapy was followed in 189 patients. Renal scarring or decreased kidney function were shown in 15. 12% respectively. Renal damage was identified as a risk factor for poor prognosis (p-value <0. 005) only for renal function deterioration. Patients with high-grade VUR required surgery in a significantly greater proportion (p <0. 005) due to recurrent febrile UTIs. Conservative strategy is a feasible treatment for primary VUR in children. The majority of cases could be managed conservatively with good outcomes after long-term follow-up. Decreased renal function is more frequent in patients with high-grade VUR. Renal damage at diagnosis increases the risk for surgical treatment.
